HAND HEAD-MACHINE.

Specification of Letters Patent No. 30,024, dated September l1, 1860.

To all whom it may concern:

Be it known that I, CHARLES B. Huron- INsoN, of the city of Auburn, in the county of Cayuga and State of New York, have invented a new and useful Improvement in Machines for Making Heads for Barrels, Tierces, Hogsheads, &c.; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, and the letters appended thereto, making a part hereof, in which- I Figure l, is a front view of the machine; Fig. 2, is a side view of the same; Fig. 3, is a top, or birds-eye view, and Fig. 4, is the crane, or pier detached; showing the center-points, or screws N, N, the cutter head, L, and the circular cutters O, O, which are placed, and fastened in the same; the beveling chsels, or cutters g, g, and one of the projections M, which support the crane, detached, and turned down to show the indentations K, for the center-points, and which, by being changed from one to another, adapt the machine to heads of different sizes, and in combination with the set-screw g, varying the position of the face plate or disk y, gives the desired bevel to large, or small heads.

Similar letters of reference indicate corresponding parts in each of the several figures.

A, is a strong cast-iron frame the contour of which is substantially as represented, and in which are the bearings and nuts for the shafts which support and move the clamp disks B, B, the projections M, M, that support the swing crane orpier C, and all the other working parts of the machine.

B, B, are two circular clamp disks between which are to be placed the pieces of board or heading stuft'. Those disks are opened or held and pressed firmly together by the screw, el, and the hand wheel a, and are turned on their aXis at the pleasure of the operator.

C, Fig. 4, is the swing crane or pier which is attached at its top and base to project-ions M, M, from the frame A by adjustable center points or screws N N, with set nuts on which points the crane may be swung freely to the right or left by the lever fw thus obtaining a horizontal circular motion and by a change of the points it is adapted to heads of larger or smaller diameters.

Upon the top of this crane or pier is mounted the saw arbor f, Fig. 4, and upon the extreme end of it is placed the concave, circular saw S, and upon its inner face the cutter head 7L, in which are made slots for the insertion of the new and peculiarly constructed circular cutters O, O, Fig. 4. These cutters correspond exactly with the concavity of the saw as shown at D, Fig. 3, and are therefore easily put in and taken out on the curvature of the saw and are held firmly in their places by the set screws n, n. By this arrangement two advantages are gained viz., ease of adjustment and constant accuracy of position however much they may be worn.

F, Fig. 3, is a curvilinear locking bar, projecting from the main frame, and passing through a slot in the pier; it has notches in which the lever w, catches, and thus iXes the saw, either into, or out of, the work as may be necessary.

G, Fig. l, is a lever projecting from each side of the main frame having dogs o, Fig. l, which support the heading stuff when being placed between the clamps. These dogs may be raised, or lowered, to suit varying sizes of heads, and removed at once whenever the stuff is clamped.

From the foregoing description of this machine, and the drawings thereof, to which reference is made, its construction and mode of operation will, I trust, be easily, and distinctly seen, yet to guide the operator in its use, I will concisely state, that the pieces of `heading stuff, cut of suitable lengths, are

dropped between the clamp disks B, B, and rest upon the dogs 11,11. These disks are then immediately and firmly pressed together, by turning the hand-wheel a, and the dogs removed by the lever Gr, the concave saw, already in motion by the belt m, is then swung into the work, as shown at z5, Fig. 3, and when it has cut through the stuff the eX- treme end of the lever, 10, enters the inner notch of the locking bar F, and thus fixes the saw in its place. The operator then gives the disks one revolution, which completes the work leaving the heads neatly sawed, beveled and fit for use.

What therefore I claim as new, and desire to secure by Letters Patent, is-

l. The cast iron frame A supporting all the Working parts, and constructed subSt-anndentations K substantially as described tally as, and for the purposes speoed. and for the uses and purposes set forth. 2.
